Detailed Product Description

This DFC Brake Rotor - Drilled and Slotted - Silver is part of Dynamite Friction's DFC line, which focuses on delivering rotors with enhanced braking characteristics through drilled and slotted surfaces. The drilled holes and slots help reduce brake fade by allowing heat and gases to escape more efficiently during heavy braking. The rotor’s plain disc finish combined with a zinc silver coated hat provides a balance of performance and corrosion resistance, making it suitable for daily driving and spirited use.

With a nominal thickness of 26 mm and a discard thickness of 23.4 mm, this rotor maintains structural integrity and safety throughout its service life. The directional surface design ensures optimal contact with brake pads, improving braking response and pad wear. The rotor’s dimensions and bolt pattern are engineered to fit Mercedes-Benz CLS53 AMG, CLS450, E43 AMG, E53 AMG, E400, and E450 models, ensuring precise fitment and reliable operation.

Compatible Vehicles and Applications

This rotor is compatible with the following Mercedes-Benz models:

• CLS53 AMG
• CLS450
• E43 AMG
• E53 AMG
• E400
• E450

It is designed to address common braking issues such as:

• Brake fade during high-performance or heavy braking conditions
• Uneven pad wear caused by heat buildup
• Corrosion and rust on rotor surfaces
• Vibration or noise due to rotor surface imperfections
• Reduced braking efficiency from glazed or worn rotors

Installation Notes and Tips

When installing the Dynamite Friction 631-63166R rotor, ensure the rotor surface is clean and free of any protective coatings before mounting. Verify the bolt hole alignment with the vehicle’s hub and torque bolts to manufacturer specifications. Because this rotor features a directional surface, confirm the rotation direction matches the vehicle’s wheel rotation to maintain optimal performance. It is recommended to replace brake pads simultaneously to ensure even wear and braking efficiency.
